GetAutoChecks the internal cache for an appropriate entry, and if none is found reads 
field
to see if it contains integers, floats or strings, and then calls one of the other methods in this class to get the values. For string values, a StringIndex is returned. After calling this method, there is an entry in the cache for both type 
AUTO
and the actual found type.
GetCustomChecks the internal cache for an appropriate entry, and if none is found reads the terms out of 
field
and calls the given SortComparator to get the sort values. A hit in the cache will happen if 
reader
, 
field
, and 
comparator
are the same (using 
equals()
) as a previous call to this method.
GetFloatsOverloaded. Checks the internal cache for an appropriate entry, and if none is found, reads the terms in 
field
as floats and returns an array of size 
reader.maxDoc()
of the value each document has in the given field.
GetIntsOverloaded. Checks the internal cache for an appropriate entry, and if none is found, reads the terms in 
field
as integers and returns an array of size 
reader.maxDoc()
of the value each document has in the given field.
GetStringIndexChecks the internal cache for an appropriate entry, and if none is found reads the term values in 
field
and returns an array of them in natural order, along with an array telling which element in the term array each document uses.
GetStringsChecks the internal cache for an appropriate entry, and if none is found, reads the term values in 
field
and returns an array of size 
reader.maxDoc()
containing the value each document has in the given field.
